RH7.3 manpage is quiet old, btw.

Linux manpages-1.54 (Dec 30 2002):

The (Linux-specific) SHM_REMAP flag may be asserted in shmflg to indi-
cate that the mapping of the segment should replace any existing map-
ping in the range starting at shmaddr and continuing for the size of
the segment. (Normally an EINVAL error would result if a mapping
already exists in this address range.) In this case, shmaddr must not
be NULL.
